2nd Time at the track, 1st time I ran I was stock w/ 19's
After Popcharger, Test Pipes, Exhaust, Plenum Spacer, UR pulley I managed 1mph and pretty much no improvement on times

STOCK MODS
60' - 2.49 2.27
330 - 6.41 6.19
1/8 - 9.58 9.37
MPH - 77.78 77.41
1000 - 12.29 12.06
1/4 - 14.58 14.32
MPH - 99.9 100.8

I feel that goin NA was the worst decision I have ever made
Any tips or anyone that wants my car

P.S. NSX's and 05 GT's were running 14.4's

 

practice practice. that 60 ft isnt that good

 

that wasn't my point, but thanks

 

damn Dana, all those mods and still can't beat my time on bald tires and a crappy 60ft? it's because you still dont have the nismo bumper!

 

Wow-sooo much potential you just have to keep praticing. With a mods list like that Id be upset with higher than 13.5. Practice, practice practice, its the best thing you can do...

 

This isn't true all of the time, but a real general rule of thumb is that .1 off of your 60' equals .2 off of your 1/4 time. Work on that 60' Fix that and you'll be much faster.

 

Very strange.

Looks like the biggest reason your time is that slow is the track you were running at. You can easily tell by looking at what other cars are running. GTs and NSxs running 14.4s should tell you right there that the track was slow. Those cars are normally solid 13s.

 

hey man thats good enough i went to the track last month i didnt do so good 14.22 stock (it was my first time and still was practicing my shifting and launches + it was close to 100 degress outside I didn't even let the car cool)....The best thing about was that i had much of fun

 

I think i went to a stupid track to an STi ran 15.2 i was like what!! He can't drive worth a **** and then after him I went up with this civic thats when i ran a 14.22

 

I would prefer to see some slips instead of numbers but...

I never see a bad run. All see is potential. Look at the last 660 feet of run #2: you are picking up 23 mph! Outstanding. And you already know that 60-foot times are a problem. Your speed at the 1/8 miles is lacking.

8 out of 10 new racers must:

Get that 60-foot time down to 2.0 seconds
Work on first and second gear shifts. Yes I know that redline comes fast, but you can do it. Best of luck.

 

He's picking up 23mph but he's covering the last 1/8 mile in 5.0sec. That's exactly what I did in my bone stock Z.

In my experience mph gain is not as telling as how fast you cover the last 1/8.

 

I don't think he really that upset about his times, but about his improvements compared to stock/19 inch tires. In that case I'd be pissed too. Think about this way, let us say he ran a 13.9@101mph stock, then added all those bolt ons and only ran 13.9@102mph, I'd be pretty upset myself. How were the conditions, the same? Same track?

Before you put the for sale sign up on your Z, make sure it's running properly, forget about the E.T.s, it's trap speed that worries me. Your case is not normal, other Zs who went the NA route have shown improvements, so just make sure your Z is running correctly, you may need a tune.

 

I agree...
It could be the track conditions. I've seen conditions affect trap speed by as much as 5mph. And we're not talking just temperature and elevation. Humidity is also a big factor. Some cars are just more sensitive to it than others.
Different tracks even around the same area can also affect your times.

For example, I run at two different tracks Atco raceway and Englishtown, and Atco is noticeably faster. Trap speeds are 1-2mph faster and traction is superior. Mind you, both tracks are located in NJ.

 

well, I don't care what your point was, lol. with 60' times crappy like that, you'd still be disappointed even if you went FI. You need to get those 60' times improved and your ET's will improve significantly.

I was able to pull a 2.050 60' on street tires at 30psi n/a......you can do the same or better man.

 

That's what I'm talkin about....You can rag on me as much as you want with my 60' being that I've been to the track twice. I am trying to get across the fact it took me exactly 5 seconds to end the 1/8 each time.

 

First and foremost the NA mods you have done to your Z arent exactly known to work miricles.

The Z dose not respond well to bolt on mods. But with that being said you should have gained 2-3 mph with your mods. Not just 1 mph..

Also you have to really compare the times with the slips. For example...Last time you may have trapped 98.11 mph...Then this time say you trapped 99.93 mph. Yes it only looks like a 1 mph differance but really you gained almost 2 mph...

I have done the exact same thing after doing several mods. I went to the track expecting huge improvements and left the track puzzled that my mph was only 1-2 higher......Not realizing that the time I ran before my new mods I was under an 1/8 tank of gas and the Density altitude was very good..

But when I went with my new mods My car was 3/4 a tank of gas and the density altitude was not as good. making what i was sure would be a 3-4 mph improvemnet barely be a 1-2 mph improvement...

But then with the same mods on a different night with an 1/8 tank of gas again and weather that was the same or better than the night I ran before the new mods I saw that the car actually did pick up a solid 4 mph...

Dont let one night throw you off......Some nights I trapp 108-109..Some nights i trap 110-111....The weather plays a huge roll in your trapp speeds.With your mods and your minimal results Id guess weather was the culprit before an actual fault in the car....

TRUST ME..IF YOUR WIRES ARE BAD OR SOMTHINGS ACTUALLY WRONG YOUR NOT GONNA TRAPP 1 MPH HIGHER....

Its all about baby steps...the first mod that I did to my car cost me 3 grand and I was expecting a solid 7 tenth and 7 mph improvement....I ended up with a 4 tenth and 4 mph improvement.....Then changed one of the parts i spent big money on for somthing else...Then got the pcm able to handle those changes...

This took a solid year of dynos and tuning 1/4 miles. But now the car trapps 8 mph higher than when it was stock. Dont give up......Dont sell the car.....It will come together.

 

Very good post
